'verstärken' and 'neutralisieren' are opposites when it comes to the effect of something. 'verstärken' makes an effect stronger or more intense. 'neutralisieren' cancels out an effect or makes it much weaker, often through an opposite effect. The word 'neutralisieren' sounds somewhat more technical and fits well in chemistry, technology, or also in figurative situations. In practical terms: 'verstärken' adds more effect, while 'neutralisieren' takes the effect away.
